smoking (Rosas et al., 2007; Steele et al., 2005). The samples of lung biopsy from individual
with early asymptomatic lung disease exhibit several histologic subtypes of interstitial lung
disease (ILD) (Rosas et al., 2007). A familiar risk factor for few idiopathic interstitial
pneumonias including IPF is cigarette smoking (Baumgartner et al., 1997), it may result in
subclinical parenchymal lung disease that is observable by spirometry and computed
tomography (CT) imaging, even amidst a conventionally healthy cohort (Lederer et al., 2009;
Washko et al., 2010). A high-resolution CT (HRCT) scanning emerges to be more sensitive
than measurements of pulmonary function and cardiopulmonary exercise test parameters in
recognizing subjects with asymptomatic ILD (Rosas et al., 2007).
It is uncertain presently that how patients with incidental, subclinical IPF should be
attended and supervised. It is significant to have enhanced comprehension since the
prevalence of subclinical IPF is probable to expand with expanding tendency in the operation
of chest CT imaging for non-ILD diseases, like the diagnosis of pulmonary embolism and
coronary artery disease. Considering the comparable low prevalence of IPF and deficiency of
successful therapies, it is also unknown how to recognize those at high risk for progressing
IPF in the general population and if the screening attempts to modify the results perceive in
the subclinical stage IPF. It is probable additionally that subclinical IPF is not a benign
procedure. The subclinical IPF may be exhibited as a risk factor for the progression of acute
aggravation, basically after invasive process or (Chida et al., 2008; Araya et al., 2008;
Takeda et al., 2008) .
2.2.7.2 Slowly Progressive IPF
In the IPF’s traditional phenotype there is gradually continuous decrease in the lung
function and aggravating dyspnea causing death within some years of diagnosis (Selman et
al., 2007; King et al., 2001b). In aggravating disease the mean annual rate of decrease, ranges
from 0.13 L to 0.21 L as measured by the FVC (King et al., 2008; Raghu et al., 2004; Azuma
et al., 2005; Demedts et al., 2001; Taniguchi et al., 2010; Raghu et al., 2008; Daniels et al.,
2010). It is observed that the gradually continuous clinical path may basically be less usual
than classically defined. According to a current population-based cohort study in Olmsted
County, Minnesota, 47 incident cases of IPF were evaluated over a term of 9-years and
